Learning Download: How to Grow Thunbergia
Thunbergia is native to eastern Africa, and it is a climbing plant. Since it is a vining plant, it can grow well in fence rows, on trellises, mailbox posts, in a hanging container or up lampposts.
Before Planting: The seeds are sown directly into the garden, but they can be started indoors six to eight weeks before the last frost. Amend soil with compost prior to planting.
Planting: Wait until the last frost has passed before directly seeding. Thunbergia seeds will take a while to germinate, up to 25 days.
Watering: Thunbergia does not tolerate drought well, so this is something to look out for especially in you are growing them in containers.
Fertilizer: Adding a general-purpose fertilizer every 4 to 6 weeks.
Days to Maturity: Thunbergia flowers will bloom from summer through fall.
Harvesting: Since they are a vining pant, these flowers are not great to harvest and display indoors.
Tips: These plants grow well in full sun or light shade, however, if you are planting them in a hotter region, it is best to make sure the plants receive afternoon shade.
